G. E. Moore

George Edward Moore, (4 November 1873 – 24 October 1958) was an English philosopher. He was, with Bertrand Russell, Ludwig Wittgenstein, and (before them) Gottlob Frege, one of the founders of the analytic tradition in philosophy. Along with Russell, he led the turn away from idealism in British philosophy, and became well known for his advocacy of common sense concepts, his contributions to ethics, epistemology, and metaphysics, and "his exceptional personality and moral character." He was Professor of Philosophy at the University of Cambridge, a highly influential member of the Bloomsbury Group, and the editor of the influential journal Mind.
